The US Department of Transportation Pipeline and Hazardous Materials Safety Administration (PHMSA) Office of Hazardous Materials Safety has updated all guidance documents and references on its webpage to reflect the currently accepted practice of using in vitro corrosion test methods wherever possible. Due in large part to efforts by PETA, PHMSA's website, letters of interpretation and all other materials on this issue have been updated to reflect recent amendments made to the United Nations Recommendations on the Transport of Dangerous Goods Model Regulation and OECD guidance documents. Previously-issued letters and positions have been replaced by the current position which promotes to the extend possible the use of in vitro skin corrosion test methods.
